I can't help but notice the white ink, even multi layered, is not very bright. It looks like a 5% gray to me. We use it on clear acrylic as a backing coat, and the overall colors don't punch much because of this. We tested applying white paint instead of using the white ink over the colors and we can see a big improvement (=not linked to color profiles).

We have used 4 or 5 white cartridge to date, and this 'problem' is consistent. Is this anyone can help me with ?
